Wash your hair with a silicone-free shampoo like khadi Hibiscus Shampoo. 

Stir the powder of khadi plant hair color with 50 degrees warm water until you get a smooth cream. Distribute it evenly in your hair with a brush: strand by strand to the tips. If you only want to dye your roots, leave out the lengths and tips.

Leave the plant hair color medium brown between 30 and 120 minutes. The longer it is left on, the darker the color result will be. If you have already dyed with this shade and just want to refresh your color, leave the color in your hair for 15 to 30 minutes.

After the exposure time, rinse the plant hair color with clear water. Please do not use shampoo for 24 to 48 hours, because in this time the color depth of your Khadi nuance unfolds completely.

Then, before the first wash with shampoo, use a khadi hair oil to fix the color pigments. Leave the oil on for at least 20 minutes and then wash it out with a natural shampoo. This way your khadi shade will last longer.

Of course you can also mix khadi plant hair color medium brown with other khadi hair colors:

    with senna/cassia or a khadi blonde shade to refresh your brunette color.
    with khadi gold touch for light cappuccino to gold shades.
    with khadi medium blonde for a deeper medium blonde.
    with khadi light brown for richer results.
    with khadi dark brown for a darker, cooler shade.
    with khadi black or indigo for a deeper color result.
    with khadi henna or other khadi red tones for reddish brown to mahogany.
